Measure how much of a air freight allocation is being used by weight and by volume. The calculator identifies the more constrained dimension, shows remaining capacity, and flags an overload when either input exceeds the capacity assigned to the shipment. Use payload and usable cargo-space figures after operational restrictions. The result supports load planning, but it does not assess cargo compatibility, stacking, balance, or securing requirements.
Weight utilization = Used weight ÷ Available weight × 100
Volume utilization = Used volume ÷ Usable volume × 100
The main result is the higher of weight and volume utilization because that dimension becomes the first practical capacity constraint.
Capacity percentages do not confirm safe loading. Follow carrier, equipment, balance, dangerous-goods, and cargo-securing requirements.
For 7,200 kg in a 10,000 kg allocation and 42 m³ in 60 m³:
Weight = 72.00%; Volume = 70.00%; limiting utilization = 72.00%
A shipment can reach its weight limit before its volume limit, or vice versa. The higher percentage is the binding utilization.
Yes. A result above 100% signals that the entered used weight exceeds the stated available weight and the plan is overloaded.
Use cargo capacity available to this shipment after tare, operational restrictions, and reserved space, not gross equipment capacity.
Remaining weight and volume equal available capacity minus used capacity. Negative values indicate the amount over capacity.
Not necessarily. The percentage measures occupied volume, but it does not evaluate stability, compatibility, shape, or load-securing quality.
